Zuto Doo was a male Quara Aqualish who served as a crewman aboard the starship known as the Woebegone.
During a voyage originating from Bal'demnic and bound for Ithor, Zuto Doo and his fellow crew members discovered that a Muun had secretly boarded the Woebegone. Following some discussion, the crew made the choice to exit hyperspace and get in touch with officials from Bal'demnic to determine if the Muun was a wanted individual. However, the Sith Lord Darth Plagueis, who was in reality the Muun hidden on board, launched an assault on the crew because he wished to keep his activities on Bal'demnic secret. Zuto Doo perished in the conflict with Darth Plagueis.
